Question

Which of the following relations represents the correct mathematical form of Ohm’s law?

• A. I = V2/R
• B. V = IR
• C. I = R/V
• D. R = I/V

Answer 1

Answer:

B. V = IR

Ohm’s law states that the voltage across a conductor is directly proportional to the current flowing through it, represented by the formula V = IR where V is the voltage across the conductor, I is the current flowing through the conductor and R is the resistance provided by the conductor to the flow of current.
